Men in suits relaxing in the grass at the 1955 Farnborough show. The crude Sperrin had been developed as a backup in case the V bombers failed. It had two pairs of engines stacked above each other. This is the second of the two prototypes built, which served as research aircraft.

With D.H. Gyron engine in each lower nacelle.

The first of the two Sperrin test aircraft lands over the heads of the Farnborough SBAC show crowd after its display. Note unusual engine arrangement of two in each bay, one above the other. The lower port enlarged nacelle houses the powerful Gyron engine, which was being tested in the aircraft.
